It’s hardly a surprise given that the show continues to pull in a large audience even after 15 seasons, but CBS has renewed “NCIS” for a 16th season, which will unspool during the 2018-2019 broadcast season.

The network noted that the show is CBS’s No. 1 drama and the most-watched drama in the world.

Meanwhile, series star and executive producer Mark Harmon has inked a new agreement to remain with the series.

“It’s pretty simple — viewers everywhere love NCIS,” said Kelly Kahl, President, CBS Entertainment. “This show speaks to viewers of all ages, in all parts of the country and around the world. NCIS’ amazing characters and terrific storytelling result in some of TV’s most passionate fans. Of course, none of this would be possible without an outstanding production team, and talented cast led by the incomparable and absolutely tireless Mark Harmon. We’re thrilled he is returning as the centerpiece of the show, and we could not be more excited for NCIS’ 16th season.”

The announcement notes that “NCIS” is averaging 17.0 million viewers this season and ranks as one of the five most-watched shows on broadcast television.

“On the digital front, ‘NCIS’ is one of the most-watched prime-time series across CBS’s digital platforms, including CBS All Access and in the Electronic Sell Through (EST) market,” CBS notes in the announcement. “The series also continues to be a powerhouse in the global market, licensed in more than 200 territories. It currently holds the title of ‘the most-watched drama series in the world,’ having received the International Audience Award by Eurodata TV Worldwide and the Monte Carlo Television Festival.”

The show has also done well in syndication.

“In syndication, previous season episodes of ‘NCIS’ are cable television’s most-watched off-network drama, out-delivering the next closest competitor by +23%,” CBS notes. “‘NCIS’ is also cable’s second most-watched off-net series, behind only ‘The Big Bang Theory.'”

Following its premiere in 2003, “NCIS” became the No. 1 scripted drama on television during the 2009-2010 broadcast season, and has remained the No. 1 drama every season since.
